A meter stick on a horizontal frictionless table top is pivoted at the 80-cm mark. A force F1 = 5 N is applied perpendicularly to the end of the stick at 0 cm, as shown. A second force F2 (not shown) is applied at the 100-cm end of the stick. The stick does not rotate.

a) What is the torque (magnitude and sign) about the pivot from F1?

b) Explain why the torque from the pivot about itself is zero.

c) What is the torque (magnitude and sign) about the pivot from F2?

d) If F2 is applied perpendicularly to the end of the stick what is its magnitude?
